Credit Ratings, Collateral and Loan Characteristics: Implications for Yield
Posted: 9 Sep 2002
This paper studies how collateral affects bond yields. Using a large dataset of public bonds, we document that collateralized debt has higher yield than general debt, after controlling for credit rating. Our model of agency problems between managers and claimholders explains this puzzling result by recognizing imperfections in the rating process. We test the model's implications. Consistent with our model and in results new to the literature, we find the yield differential between secured and unsecured debt, after controlling for credit rating, is larger for low credit rating, nonmortgage assets, longer maturity and with proxies for lower levels of monitoring.
